Same thing happens when I have a process running that is not NFS-intensive.

Is there some additional debugging information I can enable to provide more

I intsalled 2.0-testing.  The 2.6.12-xen0/U kernel in 2.0-testing that I pulled 
this morning seems to panic right up front so I went back to the kernel.

This combination still causes the suspend to fail with the same 'Retry suspend 
domain' calls.

What I'm running in the domain will be doing a ton of NFS access (doing a build 
that uses all networked resources).  Not sure if that would come into play or 
not.  I'll try making it do something else that will be less NFS intensive to 
see if that works better or not.

The latter - although there was a bug earlier whereby even though the
message (a 'xfr_vm_suspend' message to xend) was correctly delivered,
it could get ignored by xend. This is fixed in 2.0-testing; the patch
is small though and so you could just try it on a 2.0 tree if you don't 
want to upgrade your kernels.
